 appears to be the basis of each description, and while the diag- 

 noses are apparently drawn from series of individuals, we are 

 not informed as to the number actually examined. Miss De 

 Rooij 's book is invaluable, yet one notes for instance (p. 277) 

 under the description of Tropidophorus brookei that the prae- 

 frontals are said to be in contact. Boulenger, who had but two 

 specimens when he wrote his diagnosis in the Catalogue of 

 Lizards in the British Museum (III, 1887, p. 361) says ''prae-
